At some point of the make process, one job will infinit loop (taking 100% of

some time Cygwin Terminal isn't
responsive anymore, and I'm not able to open another one or to spawn any other
processes that are relying on the cygwin dll. I was able to observe this
behaviour every time i tried
consistently.
I have repro'd this problem with the exception that there was no 100% cpu
usage. Looks like an exception handling loop:

First chance exceptions are reported before any exception handling.
